Crops of the future and sheep working as firefighters

Why do plants produce chemicals that affect the nervous systems of humans and animals? It probably gives them an evolutionary advantage – plants are easy targets for herbivores, and chemical defence allows them to survive. On the other hand, humans have learned to use chemicals produced by plants in various ways. For example, the Asteraceae family produces alkaloids, flavonoids, and terpenoids, and humans have copied and synthesised these chemicals and used them as anti-inflammatory drugs, pesticides, and antimalarials. Pyrethrin produced by chrysanthemums repels ticks and lice. Even some spices may have evolved as toxins, such as mustard oil.

What crops will we grow in the future due to climate change, drought and extreme weather phenomena? In such conditions, perennial vegetables are more accessible and sustainable to grow. Experts recommend perennial veg, dwarf Jerusalem artichokes, hopniss, perennial climbing vine,  vine spinach, moringa and Mediterranean saltbush.

Climate change is also related to the return after a long break to forest pastoralism – Europe and North America use flocks of sheep and goats to thin out the vegetation and reduce the risk of fires. Sheep appear on solar farms, vineyards, golf courses, cemeteries and green roofs. Companies are also established that take care of lawns thanks to these animals – they mow, weed, and fertilise them.

Scientists from the University of California have discovered that some individuals possess abilities that go beyond the norm and can be considered “superpowers”. For instance, sherpas living in the Himalayas have the ability to survive in an atmosphere with 40% less oxygen than sea level regions. They have evolved to maintain low levels of red […]

The Slovak National Party (SNS) is proposing a law to increase transparency in non-governmental organisations (NGOs). According to the proposed law, NGOs that receive more than 5,000 euros per year in foreign financing would be marked and labelled as “organisations with foreign support”. Additionally, SNS is also suggesting the expansion of the possibility of compulsory […]

Unmanned aerial vehicles in armed conflicts
Since the beginning of the war in Ukraine, Russia has more than doubled the production of unique systems to deter unmanned aerial vehicles (UAVs). Over the last year, the demand for such systems has quadrupled. As a consequence, private companies, particularly those in the oil and gas sector, are seeking to protect themselves from increasing […]

Bird populations in the world and the impact of human activities
A group of experts from Finland, Denmark, Great Britain, and Spain have conducted research on bird species and their vulnerability to human-dominated habitats. The study examined around 6,000 bird species worldwide and found that 80% of them are at risk of being negatively impacted by urbanization, air pollution, and climate change. While some species can […]

According to researchers from the University Hospital Essen, touch can have positive effects on reducing pain, depression, and anxiety. Whether it is a hug from a friend or a social robot, or simply wrapping oneself in a blanket, it benefits both the body and mind. However, human touch is more effective when it comes to […]
